Abstract
The utility model discloses a plane retainer unit for a slewing bearing, which comprises a sector frame body. Six holes are uniformly distributed on the sector frame body. Both upper and lower surfaces of the sector frame body are at least fixedly connected with two brackets. Due to the adoption of the plane retainer unit for the slewing bearing, relative torque force cannot be generated between a retainer and a roller. The plane retainer unit is difficult to break and is safe to use.
Description
Technical field
The utility model relates to a kind of retainer, relates in particular to a kind of retainer unit, pivoting support plane that three-row cylinder roller combination dials bearing is used that is used for.
Background technique
Three-row cylinder roller combination dials bearing is made up of inner ring, outer ring, roller and retainer, and this turntable bearing can bear bigger thrust load, radial load and tilting moment; Be mainly used in industries such as harbour machinery, lifting transportation.
General retainer all adopts the pocket hole to arrange in the same way, and layout can operate bearing in one direction like this, still, in actual use, when producing radial load and tilting moment, tends to retainer is twisted off, and uses dangerously, is easy to generate and scraps.
Summary of the invention
The purpose of this utility model is to provide a kind of increase retainer intensity, safe in utilization, the retainer unit, pivoting support plane that is difficult for scrapping.
In order to achieve the above object, the technical solution of the utility model is: retainer unit, a kind of pivoting support plane, comprise fan-shaped support body, and be evenly equipped with six holes on the described fan-shaped support body, at least respectively be fixedly connected with two supports on the upper and lower surface of described fan-shaped support body.
All be fixedly connected with support on the upper and lower surface on the described fan-shaped support body between the adjacent hole.
Described support has two supporting legs.
Has the stress groove on the corner in the hole on the described fan-shaped support body.
After adopting said structure, owing at least respectively be fixedly connected with two supports on the upper and lower surface of described fan-shaped support body, increased the intensity of retainer, support contacts with raceway in use, is rotatably assorted.Can not make the relative torsion of generation between retainer and the roller, easy-rupturing is not safe in utilization.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the A-A direction of Fig. 1,
Fig. 3 is that the B of Fig. 2 is to view.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, 2, 3, retainer unit, a kind of pivoting support of the present utility model plane comprises fan-shaped support body 1, is evenly equipped with six holes 2 on the described fan-shaped support body 1, at least respectively is fixedly connected with two supports 3 on the upper and lower surface of described fan-shaped support body 1.
As shown in Figure 1, in order better to keep balance, all be fixedly connected with support 3 on the upper and lower surface on the described fan-shaped support body 1 between the adjacent hole 2.
As shown in Figure 1, described support 3 has two supporting leg 3-1, can better guarantee that the rolling between support 3 and the raceway cooperates.
As shown in Figure 1, in order to reduce the stress on the hole 2, has stress groove 2-1 on the corner in the hole 2 on the described fan-shaped support body 1.
